Vasilisa

First imperial born within the clan, mother of the three more.

After her daughter Trina grew to her full size and strength and started showing signs of the rebellous ignorant arrogant attitude developing, the clan almost unanimously deciced it was time to stop.

Trina was, as a precaution, sent off to Lightweaver, where she'd be under better watch (hopefully glittermom has realised the error of her ways and wouldn't mind finally getting around to fixing her mistakes) and Vas herself took a breedchange option and went for the smallest variant, so that even if the imperial-emperor heritage sticks she wouldn't add much.
/True,there was also the guilt factor in this./
While the breedchanging process went, she had to hide away from everyone in fear that the magic energy she'd have to lose in the process would become a destructive wave or something of the sort.
The blast was a big one, yes, but luckily nothing that bad happened.

Now she's the main consultant beside Night for any newly accepted into the clan imperial to come to discuss their options to.

Also probably the one to conduct the breedchange procedure, as the one with the most concentration of magic power, in case something goes sideways she'll most certainly be able to help.
